Specification of Letters Patent.

Patented May 2, 1916.

Application filed December 19, 1914. Serial N 0. 878,156.

To all whom, it may concern Be it known that I, RALPH W. CUrTs, acitizen of the United States, residing at Shabbona, in the county ofDekalb and State of Illinois, have invented new and useful Improvementsin Spring-Seats, of which the following is a specification.

This invention is an improved spring seat for use on mowers,pulverizers, wheel plows and other like machines, the object of theinvention being to provide an improved spring seat of this characterwhich may be readily detached from the supporting seat bar and which iscushioned against the vertical thrusts of the seat bar incident to themovement of the machine on which the seat is used.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of a springseat constructed in accordance with my invention showing the samearranged on the seat bar of a mower or other like agricultural machine.Fig. 2 is a rear elevation of the same. Fig. 3 is a detail sectionalview.

For the purposes of this specification a seat supporting bar, which isof usual form and construction is shown at 1. The seat 2 .has aninverted U-shaped member secured transversely under the bottom andproviding a pair of spaced downwardly extending posts 3. A spring 9which is substantially S-shaped has its front end secured under thecenter of the seat at the front end of the latter as shown and has itsrear end arranged on the bar 1. On the upper side of the rear end of thespring 9 is a cross plate 4: which is secured to said spring 9 and alsoto the bar 1 by rivets 6. A pair of coiled springs 7 are arranged in theposts 3. Their lower ends are secured to the posts by nuts 8 and theirupper ends are extended inwardly and bolted under the ends of the crossplate 4 as shown. The spring coils, resiliently and yieldingly supportthe said seat and also guide its movements and serve to cushion the seatagainst shocks, vertically, longitudinally and transversely and hencecause the seat to ride easily and smoothly and greatly promote thecomfort of the driver of the machine.

Having thus described my invention, I claim 1 1. In combination with aseat supporting bar, a seat arranged above said bar, an invertedU-shaped member secured transversely to the under side of the seat andprovided with spaced downwardly extending posts arranged at oppositesides of the bar, a spring arranged longitudinally under the seat andhaving its front end secured to the front of the seat and its rear endarranged on the bar, a cross plate on the upper side of the rear end ofsaid spring and secured thereto and to said bar and coiled springsarranged on said posts, having their lower ends secured to the posts andtheir upper ends secured to said cross plate.

2. In combination with a seat supporting bar a seat arranged above thesame, a spring under said seat and secured thereto and bearing on saidbar, a pair of spaced posts extending downwardly from the seat andarranged at opposite sides of the bar and a pair of coiled springsarranged on the posts, having their lower ends secured thereto, andmeans connecting the upper ends of said coiled springs and bearing onthe first named spring.
